How to Add Ceramic Tile to a Bathroom Floor
- 1). Measure the bathroom with a measuring tape. This will ensure you have enough ceramic tiles and will allow for any mistakes in cutting, or broken tiles.
- 2). Dry-lay the tiles, setting out any patterns you want to include in the tile placement. This will allow you to mark the tiles that need to be cut before setting them. Once you are pleased with the placement of the ceramic tiles, trace around the tile in the center, using a pencil. This is your guide.
- 3). Mix the thin-set mortar according to the instructions on the package. Using a notched trowel, spread a thin layer on the floor where you marked the center tile. Hold the trowel at a 45-degree angle when applying the mortar.
- 4). Lay the first tile in the center, pushing down in the middle of the tile with a slight twisting motion to set it securely. Use spacers to keep the tiles at an equal distance from each other and to allow for grout.
- 5). Cut tiles with the wet saw, as this will prevent tile breakage. You may need to cut tiles in a circle to fit around the toilet or other bathroom fixtures. Do so by cutting notches with the wet saw right next to each other along the rounded line you've drawn on the tile. This will allow the ceramic tile to break away close to the line. Sand the rest of the tile to make the cut edge smooth. Allow the mortar to dry overnight.
- 6). Remove the spacers from between the tiles. Mix grout according to the instructions on the package. Apply grout between the tiles, using a grout float, and wipe away any excess with a damp cloth. If you are adding grout sealer, do so after the grout has thoroughly cured.
